1:03 This is an anchor "Windlass". A "capstan" revolves on the vertical axis while a WINDLASS revolves horizontally. The slot for the bar/lever is not for "additional force", it's for the ONLY force. Working the lever back and forth turns an internal ratcheting gear mechanism applying mechanical advantage. One end of the shaft has a "rope gypsy" for hauling in anchor rode by winding several wraps around it and pulling the working end to apply friction. The other end has a "chain gypsy" for hauling in anchor chain. Anchor rodes frequently utilize a combination of chain near the anchor for weight to keep the pull on the anchor horizontal across the sea floor and rope to extend the rode to further lower the angle of forces on the anchor. Most are solid bronze, though the white painted example is of a non-ferrous alloy.
The lever operates a ratchet and pawl system good mechanical advantage. Have lifted at least 300 pounds with winches The ones shown were used on navy utility boats up to sixty ft and fish boats. By Ideal Windlass originally of Attleboro MA Then East Greenwich RI All gone now
The COVID key should at least be silver plated. After receiving a nasty wound I learned that silver prevents bacteria growth. I had to "pack" rectangles of this gauze with silver into the wound.. man that hurt.
Activated Manuka honey 400+ achieves the same result and is a lot easier to deal with. Got rid of a nasty deeply ulcerated spider bite that resisted all other topical antibiotics and lingered for months by using this. Almost immediate results. 👍🏻
Copper and its alloys are more antimicrobial than silver. Thus silver plating a brass key would be more expensive and reduced its effectiveness. Steel or Aluminum keys are not antimicrobial and would benefit from sliver or even more from copper plating.
That actually reminds me of my childhood visits to my great-grandmother's place. She didn’t have running water, so we would melt snow for cooking. Storing lake ice for later use in cooking or drinking seems like a smart idea!
@@MI-MysteriousItem Here in England some of the old mansions had a special small building as an ice house. Deep hole in ground, roof covered in straw thatch to keep heat out. Collect ice from lake or river during frozen winter would keep for many months.
Yes! This is one of the first toothbrushes. It could be used on people with teeth are without teeth. It was also used as a tooth remover by barbershop dentists. The knob on top was used as a knock out drug. Now, we uses bristles instead of iron to brush our teeth, usually. Although brass knuckles were originally used for gum massage. Later use of the tool was of a sexual nature. Thanks from a new ex democrat here.
